DELTA TAU ACC-24E2A Channel output module

DELTA TAU ACC-24E2A Channel output module

MVTD 13 neutral displacement relay (see Figure 1 for the test circuit) One pole of the switch SW1 should be used to start the timer and one of the relay contacts used to stop the timer. With the relay on the minimum setting (5V) and the TMS = 1x, the variac should be adjusted to give 10V as measured at the relay terminals (27 and 28). Using the switch (SW1) the voltage to the relay should be switched from 0V to 10V and the operating time measured and recorded. The operating time should be 40s ±11% (within the range 35.6s to 44.4s).

Adjust the variac to give 100V at the relay terminals (27 and 28). 

Switch the voltage applied to the relay from 0V to 100V. Measure and record the operating time. The operating time should be 2.11s at ±5% (within the range 2.0s to 2.22s). No allowance has been made for instrument errors. 4.3.6 Timer multiplier setting (TMS) checks With the relay on the lowest setting, the multiple of the voltage setting shown in the relevant table below, should be applied to the relay. The operating time should be measured at each TMS shown, and checked to see that it lies within the range given.
